The use of saliva as a biological sample has many advantages, being especially relevant in pigs where the blood collection is highly stressful and painful, both for the animal and the staff in charge of the sampling. Currently one of the main uses of saliva is for diagnosis and detection of infectious diseases, but the saliva can also be used to measure biomarkers that can provide information of stress, inflammation, immune response and redox homeostasis. This review will be focused on the analytes that can be used for such evaluations. Emphasis will be given in providing data of practical use about their physiological basis, how they can be measured, and their interpretation. In addition, some general rules regarding sampling and saliva storage are provided and the concept of sialochemistry will be addressed. There is still a need for more data and knowledge for most of these biomarkers to optimize their use, application, and interpretation. However, this review provides updated data to illustrate that besides the detection of pathogens in saliva, additional interesting applicative information regarding pigs´ welfare and health can be obtained from this fluid. Information that can potentially be applied to other animal species as well as to humans.

Sepsis is a complex clinical syndrome triggered by an inflammatory host response to an infection. It is usually complicated to detect and diagnose, and has severe consequences in human and veterinary health, especially when treatment is not started early. Therefore, efforts to detect sepsis accurately are needed. In addition, its proper diagnosis could reduce the misuse of antibiotics, which is essential fighting against antimicrobial resistance. This case is a particular issue in farm animals, as antibiotics have been traditionally given massively, but now they are becoming increasingly restricted. When sepsis is suspected in animals, the most frequently used biomarkers are acute phase proteins such as C-reactive protein, serum amyloid A and haptoglobin, but their concentrations can increase in other inflammatory conditions. In human patients, the most promising biomarkers to detect sepsis are currently procalcitonin and presepsin, and there is a wide range of other biomarkers under study. However, there is little information on the application of these biomarkers in veterinary species. This review aims to describe the general concepts of sepsis and the current knowledge about the biomarkers of sepsis in pigs, horses, and cattle and to discuss possible advances in the field.

•Oral co-administration of dmLT with U-Omp19 increases dmLT immunogenicity.•U-Omp19 oral co-delivery with dmLT induces anti-LT antibody responses.•U-Omp19 co-administered with dmLT protects against oral challenge with LT.•U-Omp19 can allow antigen dose sparing by oral route.•U-Omp19 can be used as adjuvant in an oral vaccine formulation against ETEC. Acute diarrhea disease caused by bacterial infections is a major global health problem. Enterotoxigenic Escherichia coli (ETEC) is one of the top causes of diarrhea-associated morbidity and mortality in young children and travelers to low-income countries. There are currently no licensed vaccines for ETEC. Induction of immunity at the site of entry of the bacteria is key to prevent infection. Current approaches to ETEC vaccines include a less toxic mutant form of E. coli heat-labile toxin (double-mutant heat-labile enterotoxin -dmLT-) with both antigenic and immunostimulatory properties. U-Omp19 is a protease inhibitor from Brucella spp. with immunostimulatory properties that has been used as oral adjuvant. In this work, we use U-Omp19 as adjuvant in an oral vaccine formulation against ETEC containing dmLT in outbred and inbred mice. To evaluate antigen dose sparing by U-Omp19 three different immunization protocols with three different doses of dmLT were evaluated. We demonstrated that U-Omp19 co-delivery increases anti-LT IgA in feces using a mid-dose of dmLT following a prime-boost protocol (after one or two boosts). Oral immunization with U-Omp19 induced protection against LT challenge when co-formulated with dmLT in CD-1 and BALB/c mice. Indeed, there was a significant increase in anti-LT IgG and IgA avidity after a single oral administration of dmLT plus U-Omp19 in comparison with dmLT delivered alone. Interestingly, sera from dmLT plus U-Omp19 vaccinated mice significantly neutralize LT effect on intestine inflammation in vivo compared with sera from the group immunized with dmLT alone. These results demonstrate the adjuvant capacity of U-Omp19 to increase dmLT immunogenicity by the oral route and support its use in an oral subunit vaccine formulation against ETEC.

Long COVID, or post-acute sequelae of SARS-CoV-2 infection (PASC), manifests as persistent and often debilitating symptoms enduring well beyond the initial COVID-19 infection. This disease is especially worrying in children since it can seriously alter their development. Presently, a specific diagnostic test or definitive biomarker set for confirming long COVID is lacking, relying instead on the protracted presence of symptoms post-acute infection. We measured the levels of 13 biomarkers in 105 saliva samples (49 from children with long COVID and 56 controls), and the Pearson correlation coefficient was used to analyse the correlations between the levels of the different salivary biomarkers. Multivariate logistic regression analyses were performed to determine which of the 13 analysed salivary biomarkers were useful to discriminate between children with long COVID and controls, as well as between children with mild and severe long COVID symptoms. Pediatric long COVID exhibited increased oxidant biomarkers and decreased antioxidant, immune response, and stress-related biomarkers. Correlation analyses unveiled distinct patterns between biomarkers in long COVID and controls. Notably, a multivariate logistic regression pinpointed TOS, ADA2, total proteins, and AOPP as pivotal variables, culminating in a remarkably accurate predictive model distinguishing long COVID from controls. Furthermore, total proteins and ADA1 were instrumental in discerning between mild and severe long COVID symptoms. This research sheds light on the potential clinical utility of salivary biomarkers in diagnosing and categorizing the severity of pediatric long COVID. It also lays the groundwork for future investigations aimed at unravelling the prognostic value of these biomarkers in predicting the trajectory of long COVID in affected individuals.

Artificial intelligence‐augmented additive manufacturing (AI2AM) represents a transformative frontier in digital fabrication, where artificial intelligence (AI) is embedded not as a peripheral tool, but as a central framework driving intelligent, adaptive, and autonomous additive manufacturing (AM) systems. The objective of this Roadmap is to present a comprehensive vision of the state‐of‐the‐art developments in AI2AM while charting the future trajectory of this rapidly emerging field. As AM applications continue to expand across diverse sectors, conventional design and control strategies face growing limitations in scalability, quality assurance, and material complexity. AI uses tools like computer vision, generative design, and large language models to help solve problems in scalability, quality assurance, and material complexity, allowing for real‐time defect detection, digital twin integration, and closed‐loop process control. This roadmap brings together leading contributions from twenty internationally recognized research groups by uniting perspectives from materials science, computer science, robotics, and manufacturing. This work aims to create a cohesive framework for advancing AI2AM as a multidisciplinary science. The ultimate intent of this work is to establish a foundation for coordinated research and innovation in AI‐powered AM and to serve as a strategic entry point for future breakthroughs in autonomous and sustainable production.

Introduction Single-incision devices for the treatment of stress urinary incontinence (SUI) have been introduced in the last few years. We report a comparison between Obturator Tension-free vaginal tape (TVT-O®) and Contasure-Needleless (C-NDL®). Methods One hundred and fifty-eight women with primary SUI were scheduled to receive TVT-O® or C-NDL® and follow-up during the first year. Epidemiological information, complications, blood loss, and pain level were recorded. We also analyze stress test and quality of life. Results Sixty-three (87.5%) C-NDL® presented a negative stress test, compared with 54 (90%) of TVT-O® ( p value 0.015 for non-inferiority test). Sandvik Severity Index was 0 in 75.4% in the C-NDL® group and 87.3% in the TVT-O® ( p  < 0.015). Complication rate and degree of satisfaction were similar in both groups. Statistically, there were differences ( p  = 0.012) in postoperative pain in the TVT-O® group. Conclusions C-NDL® provides similar outcomes as TVT-O® after 1-year follow-up. It is necessary that long-term data confirm our results.

People with Alzheimer’s disease (AD) diagnosis who get informal care remain at home longer, reducing the demand for healthcare resources but increasing the stress of caregiving. Research on the effectiveness of physical training, psychoeducational, cognitive–behavioural, and health education programs in reducing the caregiver load and enhancing health-related quality of life (HRQoL) exist, but none exist about an integrated interdisciplinary program. The goals of this project are (1) to assess the Integral-CARE Interdisciplinary Program (IP) applicability, safety, effects on HRQoL, and the incremental cost-effectiveness ratio for AD caregivers; (2) to evaluate the IP applicability and cost-effectiveness to enhance the physical, psychoemotional, cognitive–behavioural dimensions, and the health education status of informal caregivers, and (3) to study the transference of the results to the public and private sectors. A randomized controlled trial will be conducted with an experimental (IP) and a control group (no intervention). The PI will be conducted over nine months using face-to-face sessions (twice a week) and virtual sessions on an online platform (once a week). There will be an initial, interim (every three months), and final assessment. Focus groups with social and health agents will be organized to determine the most important information to convey to the public and private sectors in Extremadura (Spain). Applicability, safety, HRQoL, incremental cost-effectiveness ratio, and HRQoL will be the main outcome measures, while secondary measures will include sociodemographic data; physical, psychoemotional, health education, and cognitive–behavioural domains; program adherence; and patient health status. Data will be examined per procedure and intention to treat. A cost-effectiveness study will also be performed from the viewpoints of private and public healthcare resources.

Introduction and hypothesis This study compared transobturator tension-free vaginal tape (TVT-O®) and Contasure-Needleless (C-NDL®) at long-term follow-up . Methods Non-inferiority, prospective, single-centre , quasi-randomised trial started in September 2006 and finished in April 2011 to compare C-NDL ® with transobturator vaginal tape (TVT-O®) mesh in the treatment of stress urinary incontinence (SUI) . Epidemiological information, intraoperative and postoperative complications, subjective estimates of blood loss and pain levels were recorded. We also analysed the postoperative stress test, the subjective impression of improvement using the Sandvik Severity Index and the quality of life during follow-up using the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) . Results Two hundred and fifty-seven women with primary SUI were scheduled to receive TVT-O ® or C-NDL ® and were followed up at least 3 years after the procedure . One hundred and eleven women in the C-NDL ® group (84.7 %) had a negative stress test, compared with 54 women (88.9 %) in the TVT-O ® group ( p  = 0.0065 for the non-inferiority test). The postoperative Sandvik Severity Index was 0 or better than the preoperative score in 90.7 % of patients in the C-NDL ® group and 95.4 % of patients in the TVT-O ® group ( p  = 0.0022). The complication rate was similar in both groups. There were significant differences ( p  = 0.02) in postoperative pain within the TVT-O ® group. The degree of satisfaction was not statistically significant between the two groups. Conclusions The outcomes for the C-NDL ® group were similar to those of the TVT-O ® group, adding the concept of “single incision tape” to the tension-free sling option.

Introduction and hypothesisThere is a distinct lack of literature on postoperative management after anterior colporrhaphy (AC). Our traditional postoperative protocol consisted of 24 h of indwelling catheterisation followed by 24 h of self-intermittent catheterisation. We hypothesised that a new protocol consisting of only 24 h of indwelling catheterisation might produce better results without additional complications.MethodsFrom April 2014 to July 2017, all candidates for AC were randomised to catheter removal 24 or 48 h after surgery. The primary outcome was the postoperative urinary retention (POUR) rate. Secondary outcomes included: asymptomatic bacteriuria (AB), urinary tract infection (UTI) and postoperative pain after 24 h.ResultsA total of 79 patients were recruited. Thirty-seven and 40 patients were randomised to follow the 48-h protocol and the 24-h protocol respectively. There were no significant differences in relation to the POUR rate: 3 patients (8.1%) vs 1 (2.5%) in the 48-h vs the 24-h group respectively (p = 0.346). The UTI rate was 2 (8.1%) vs 0 patients respectively (p = 0.139) and the postoperative AB rate was 3 (9.1%) vs 0 patients (p = 0.106). In the postoperative pain evaluation, the visual analogue scale score was significantly higher in the 48 h group (0.35 vs 0.13, p = 0.02).ConclusionsAccording to our results, reducing the catheterisation from 48 to 24 h after AC does not increase the risk of POUR and decreases the rate of UTI, AB and postoperative pain. This new postoperative management protocol of pelvic floor surgery would improve postoperative outcomes and shorten the stay in hospital.

Introduction and hypothesis For the treatment of stress urinary incontinence (SUI), various retropubic and transobturator techniques have demonstrated high cure rates. Single-incision tapes, such as Contasure-Needleless® (C-NDL), have demonstrated similar cure rates to the inside-out transobturator sling (TVT-O®). The aim of this study was to analyse if C-NDL® is equally as effective as an outside-in transobturator sling (Monarc®) for the treatment of SUI. Methods We carried out a prospective, single-centre, randomised trial. The results were analysed for a non-inferiority test with a minimum postoperative follow-up of 12 months. The objective and subjective cure rates were evaluated by a stress test and a postoperative Sandvik Severity Index respectively. Patient satisfaction and operative complications were registered. The cure was defined by a negative stress test and SSI 0. Results A total of 187 patients were included, 89 and 98 undergoing C-NDL® and Monarc® respectively. Epidemiological and clinical data did not show and significant differences between both groups except a high prevalence of women who smoke (15.7% C-NDL® vs 6.1% Monarc®, p 0.03). The negative stress test was negative in 72 patients (80.9%) in C-NDL® compared with 85 (88.5%) in Monarc® ( p 0.082). The SSI was 0 in 47 (66.2%) for C-NDL® and 61 (70.1%) for the Monarc® group ( p 0.01). There were 14 (16.1%) and 8 (8.3%) dissatisfied patients for the C-NDL® and Monarc® groups respectively ( p 0.068). The rate of complications was similar in both groups. Conclusions According to the non-inferiority test, C-NDL® is not inferior to Monarc® (post-surgical SSI test), but it is inferior in the comparison of a negative stress test and patient satisfaction.
